(Cl. 229-17) This invention relatesto a package.

The invention has for anobjectto provide arnovel and improved packagecomprising ad carton having an inner lining and containingilowablefsolid material andswhieli is` provided with a novel top closurehaving detachable portions which may be easily torn from the closure toform an outlet providing a pouring opening upon application of pressuretothe sides ofthe carton;

With this general object in view and such others` as may hereinafterappear, the invention consistsin the package hereinafter described andparticularlyi defined; inthe claims at the endof this specification.`

In the drawings illustrating the preferred embodiment of the invention:

Fig. 1 is a perspective view of a lined carton for forming the presentpackage showing the top closing flaps extended;

Fig. 2 is a perspective view of the present package in its completelyclosed and sealed condition;

Fig, 3 is a vertical cross sectional view of the package shown in Fig.2; and

Fig. 4 is a perspective view of the present package with portionsdetached to form a pouring opening.

In general the present invention contemplates a novel and improvedpackage comprising a lined carton wherein a portion of the lining topclosure is folded with one of the carton closing flaps in a manner suchthat the carton closing flap and the adjacent portion of the liningclosure may be detached and torn from the top closure to form an outletproviding a convenient pouring opening upon the application of pressureto the side walls of the carton.

Referring now to the drawings, the illustrated package comprises acarton having a body portion including side and end Wall panels 12, 14respectively provided with three top closing aps extended from andfoldably connected to the body panels including side ilaps 16, 18 andend flap 20, one of the end wall panels 14 being free of a closing flap,as shown. An inner lining or lining bag within the carton is fold-ed toprovide an elongated top closure, indicated generally at 24, hereinshown as being formed by folding two opposed side walls of the liningmouth portion inwardly into overlapping relation and adhesively securingthe same, and simultaneously folding opposed end walls of the liningmouth portion outwardly, thus forming hollow, laterally extended endtabs 26, 28, triangular in shape as illustrated.

ln practice the present package is preferably formed in an automaticpackage forming machine known in the trade as a double package makerwherein the lining blank is wrapped about a forming block to form a tubeand the lining end closure is made by folding extended portions of thelining against the end of the block, as described, one of the tabs, 28,being folded in against the side of the block, the other tab, 26,remaining in its laterally extended condition, as shown. Thereafter, thecarton blank is wrapped about the lining on the block, and the firstfolded Hap 20 may then be folded against ICC the end of the block.Thereafter, the side aps 16, 18'

may be folded in succession one on top of the other and adhesivelysecured together.

As herein shown, the last folded side flap 18 may be provided with alateral extension 30 foldably connected thereto and which is adapted tobe folded down against and adhesively secured to the flap-free panel 14,the tab 26 being foldeddown with the Hap 30 as shown in Fig. 2. The flap30 is preferably secured to the panel 14 by relatively small bondingareas of adhesive, indicated at 32, to provide a frangible anchoragereadily breakable to facilitate Subsequent detachment of the hap fromthe panel 14, and the fold line between the iiap 30 and the side flap 18may and preferably will be weakened by providing spaced perforations orslits along the fold line, as indicated at 34, to facilitate subsequenttearing of the flap 30 from the carton when opening the same. In someinstances the lining tab 26 may also be provided with a weakened linealong its fold line to facilitate tearing of the same. It will beunderstood that the end closure, above described and herein referred toand used as the top closure in the completed package, is actually therst formedf-end. closure, the lined package being subsequently removedfrom the forming block, lled upside down, and provided with the nal endclosure comprising the bottom closure in the completed package.

yFrom the description thus farit will be seen that in use the tiapportion or extension 30 may be easily detached by breaking the seals atthe bonding areas 32 and that thereafter the extension 30 together withthe tab 26 may be torn olf the container along the fold lines thereof,thus forming an outlet comprising a slit opening along one edge of thetop closure which provides a pouring opening 33 upon application ofpressure to the sides of the package adjacent the ends of the slit, andthrough which the contents of the package may be poured, as shown inFig. 4. Upon release of pressure against the sides of the carton, theresiliency of the carton forming material will cause it to spring backto its initial position, thus effecting reclosing of the pouringopening.

In order to facilitate bending or bowing out of the hap-free panel 14upon application of side pressure, the panel may be provided with alongitudinal scored or weakened line 36 intermediate the sides of thecarton, the lower end of the scored line terminating about half way downthe length of the carton and branching out in diagonal scored lines 38,40, as shown.

From the above description it will be seen that in the present structureof package the carton is provided with a novel top closure embodying thelining closure and the carton closing flaps wherein detachment of anexterior carton hap portion from the wall of the carton and tearing ofthe ap together with a portion of the lining closure forms a slit outletalong the edge of the package which may be opened to provide a pouringopening by pressure against the sides of the carton, the openingreturning to its slit condition upon release of the pressure.

While the preferred embodiment of the invention has been hereinillustrated and described, it will be understood that the invention maybe embodied in other forms within the scope of the following claims.

Having thus described the invention, what is claimed is:
